8x^2+1/9
umka2103 [35]

Answer:

A. Quartic

Step-by-step explanation:

I went to desmos graphing,

8x^2+1/9 (plug it in and looked at the line)

It shows a parabola,

y-intercept: (0,0.111)

"Cubic functions. Three points not in a line determine a parabola, a polynomial function of degree 2. Polynomials of degree 2 are quadratic functions. Their graphs are parabolas."

Therefore, this is a quadratic ( quartic) since the degree in this parabola is 2.
